IMPROVEMENT IN EARTH-SCRAPERS.

Specification forming part of Letters Patent No. 133,825, dated December10, 1872.

To all whom it may concern:

Be it known that we, HENRY BOWEN and JAMES HANNA, of Adrian, in thecounty of Lenawee and State of Michigan, have invented a new and usefulImprovement in Combined Excavator and Carrier and we do declare that thefollowing is a true and accurate description thereof, reference beinghad to the accompanyin g drawing and to the letters of reference markedthereon and being a partof this specification, in which Figure 1 is aperspective view of our improved excavator and carrier; Fig. 2 is adetached view of the scraper; and Fig.3 is a detached view of thecylindercarrier.

Like letters refer to like parts in each figure.

The nature of this invention relates to an improved construction of anexcavator and carrier so arranged that a scraper deposits the earth upona rotating elevator, by which it is again deposited in the carrier, thelatter so arranged that, when desired, it can be driven to any desiredpoint and emptied, the rotating elevator forming, with the axle orshaft, a convenient carriage.

In the accompanying drawing, A is a frame to which the draft-pole A issecured. To this frame, by means of suitable boxes I), the axle or shaftis secured in the usual way. Rotating upon this axle is the elevator (3,consisting of two wheels, 01, secured together by cross-bars h. Betweenthese wheels, and secured at each end to them, are the elevatorbuckets70, set eccentrically to the shaft, and so arranged relatively to thescraper and the carrier that they will, in the forward rotation of theelevator, convey the earth taken up by the scraper and deliver thesameinto the carrier. D is the scraper, drawn by means of the arms mfrom the axle and so arranged that it may be raised from or 10 weredintothe ground, as desired. The scraper is provided with a foot-board, n,upon which, when the scraper is in use, a man should stand to keep thescraper in the ground. E is a cylinder or carrier rigidly secured to theaxle or shaft within the elevator, and it is provided with an opening,t, through which the earth is deposited in the rotation of the elevator.F is a clutch, onehalf of which is secured to the side of the elevator,while the other half is sleeved on the shaft in the usual manner.

When the carrier is full, and it is desired to empty the same in anyparticular place, the two parts of the clutch are engaged and thescraper elevated, when the elevator and carrier rotate together and theearth is emptied out of the latter when in its rotation the opening ispresented downward or toward the ground. The clutch should not beengaged until the machine has reached the dumpingground, the elevatoracting as a carriage.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. The elevator 0, consisting of the wheels d united by the cross-bars hand buckets k, the buckets being eccentrically arranged relatively tothe shafts, as described.

2. In a machine of substantially the described construction, thecombination of the elevator, constructed as described, with the scraperD, provided with the foot-board n, as and for the purpose described.
